COVERED HOLLOW WARE.

Application filed July 9, 1

To all whom it may concern:

Be it known that I, CHARLES CLARKE- BRUFF, a subject of the King of Great Britain, residing at Coalport, England, have invented certain new and useful Improvements in Covered Hollow a t are. of which the following is a specification.

This invention relates to improvements in and relating to covered hollow ware, and being particularly applicable to fictile articles it will be hereinafter described in that application.

Lids or covers of fictile articles necessarily have to be made somewhat slackly fitting to allow for varying shrinkage during the firing stage of their manufacture: hence the lids or covers easily fall oif, and in pouring out liquids from such articles as tea-pots, coffeepots and the like there is a tendency for the liquid to overflow at the top. Various means have been proposed from time to time for preventing the lids or covers from falling off their vessels during tilting of the vessels, for example, such vessels as tea-pots, coffeepots, &c., and it has been proposed to provide on the lid or cover a lug or sloping part or groove which is adapted to engage under or over a rim or flange or in a recess of the vessel; in particular it has been proposed to provide a groove or recess upon the interior of the vessel at the front to interlock with a corresponding projection on a lid or cover with lip or verge when this lid or cover slides forward upon the vessel being held at an inclination in the act of pouring out the contents, so that the lid or cover shall be held at the interlocking points while the back of the lip or verge coming against the interior of the neck of the vessel prevents the lid turning upon the center of motion formed by the interlocking means on the lid or cover and the vessel, at the front, respectively.

By such last mentioned means. as the lid or cover starts to fall forward from the mouth of the vessel during tilting of the vessel there is established between the neck of the vessel and the displaced lid or cover an interlocking relationship which can only be broken down by setting back the lid or cover to releasing position, and the present invention aims to provide improved means of this character.

An object of the present invention is twofold; firstly to obviate the falling off of covers while in use and second to confine the out-pour of the liquid to the proper out- Specification of Letters Patent.

Patented Mar. 8, 1921. 920. Serial No. 395,083.

let, for example the spout of a tea or coffeepot, this two-fold object being realized by sloping the mouth of the vessel so that it rises to the highest point on the delivery side of the vessel, and so that, in relation to a horizontal setting of the mouth, the point nearest the delivery side of the vessel is set back relatively to that side. In this way when the position of the vessel is changed a higher level of liquid can be accommodated before the liquid can overflow at the top, and a greater change f position of the vessel is possible before the line of direction or vertical line of the lid or cover falls without its base on the vessel.

For the purpose of enabling the improvements under the present invention to be more readily understood, reference is hereinafter made t the accompanying drawings in which an application of the invention to a tea-pot is shown and in which Figure 1 is a view in profile and partly in section of a tea-pot provided with a lock or safety lid in accordance with the present invention.

Fig. 2 is a plan view of the neck of the tea-pot.

Fig. 3 is an inverted plan view of the lock or safety lid.

Fig. 4 is a similar view to Fig. i of the tea-pot after suffering a change of position of about 90. I

In carrying the present invention into practical effect it is convenient, in order to insure, each and every time, a proper lockable positioning of the lid or cover on the vessel, to give the lip or verge a of the lid or cover Z) an irregular outline or contour, and to correspondingly s ape the mouth 0 of the vessel (Z. i

For this purpose a suitable outline for the mouth a is a large segment of a circle as shown in F 2. The lip or verge a of the lid or cover I) is made to correspond approximately in outline with the segmental mouth 0, but so far short of exact correspondence that the lid or cover I) is free to move somewhat toward the straight portion of the mouth 0.

On opposite sides of a diameter running parallel with the straight portion of the mouth 0, the lip or verge a. of the lid or cover I) is provided with reversely sloped parts 6 and f (hereinafter called heel and toe parts respectively) which are so proportioned in relation to the mouth 0 of the vessel. (Z that if the heel, e is inserted under a corresponding portion of the neck 9' of the vessel d as shown in Fig. 1, the restof the lip or verge a may be inserted into the mouth 0 by a hinging down movement of the lid or cover 6 about a medial bearing point of the angle between the heel 0 and the flange of the lid or cover I) as a fulcrum, the toe f clearing the straight portion of the mouth 0. By like but reverse movements of the lid or cover 7), this may be lifted out. Stops adapted to co-act with the equivalent on the vessel of such reversely sloped parts are within the ambit of the present invention.

In the vessel illustrated, viz., a tea-pot, the heel and toe parts a and f and the segmental mouth 0 are planned to be centrally cut by a vertical plane which passes medially through the spout and the handle, and that portion of the neck 9 of the vessel (Z which faces the toe part f is so formed or figured or recessed that as the lid or cover 1) starts to drop away from the mouth of the vessel during tilting of the vessel to pour out its liquid contents, the lid or cover 6 is allowed to move somewhat toward the delivery side of the vessel. In doing this as shown in Fig. 4, the toe part 7" passes under the straight portion of the mouth 0 until it contacts therewith, but at the same time the heel part 0 remains underhanging the mouth of the vessel. Thus both heel and toe parts are caused to underhang the mouth of the vessel at the same time, and the lid or cover is thereby held securely on the vessel, even if this is completely inverted, by the double lock thus formed, release of the lid or cover from this double underhang only being possible by setting back the lid or cover to the inserting or releasing position illustrated in Fig. 1.

In cases where the conditions of manufacture allow, or so far as these conditions allow, a desirable firm seating of the lid or cover on the vessel may be realized by arranging the bottom 0% the toe part 7, when the lid or cover is applied to the vessel, to bear on the neck 9 of the vessel as shown in Fig. 1, the lock still stepping in as the lid or cover in falling moves downward and outward as shown in Fig. 4.

For greater security the heel part 0 is made somewhat deeper than the toe part f.

Locking means substantially as hereinabove described is especially suited for application to fictile articles, but the application to covered hollow ware in general is to be regarded as included in the scope of the present invention.

As realizing the further two fold aim of a safety lid on the one hand, and confining the out-pour of liquid to the proper outlet on the other, Figs. 1 and i depict also the sloping of the mouth of the vessel so that it rises to the highest point on the delivery side of the vessel and so that, in relation to a horizontal setting of the mouth, a rise of level represented by the distance between the lines 0a-m and y, y, Fig. 1 is possible before the liquid overflows at the top, while Fig. 4: indicates the greater change of position which is allowable before the line of direction or vertical line of the lid or cover falls without its base.

What I claim is:

1. A covered vessel, including in combination, a vessel component, and a cover component, said cover component having a rigid verge at the front and back formed with rigid heel and toe projecting portions, and said vessel component having a mouth from front to back smaller than said rigid verge from front to back to form eventual overhanging portions for said heel and toe projecting portions of said rigid verge simultaneously, said mouth allowing said rigid verge to enter freely by first inserting the heel obliquely and then tilting down the cover component, or to leave freely by reverselike movements, but producing a double lock of the said rigid verge at the heel and toe when the cover component is displaced toward the delivery side of the vessel component.

2. A covered vessel as claimed in claim 1 having the said rigid verge contoured irregularly and the said mouth correspondingly shaped.

8. A covered vessel as claimed in claim 1 having the said rigid toe projecting portion of the rigid verge of the cover in contacting relationship with the wall of the vessel for firm seating of the cover when this is applied to the vessel.

4. A covered vessel, including in combination, a vessel component, and a cover component, said vessel component having a segmental mouth with the straight portion on the delivery side and with said straight portion formed with a lip giving toward the hinder part of the vessel, and said cover component having an approximately segmental rigid verge at the front and back formed with rigid reversely sloped heel and toe projecting portions, the side of said mouth at the back of the vessel being shaped sons to be underhung by said heel portion, said mouth allowing said rigid verge to enter freely by first inserting the 'heel obliquely and then tilting down the cover component, or to leave freely by reverse like movements, but producing a. double lock of the said rigid verge at the heel and toe when the cover component is displaced toward the delivery'side of the vessel component.

In testimony whereof I aflix my signature.
